In both superior and inferior grains, at first, the expression of OsCIN1 and an increase of hexose to sucrose ratio. Second, the expression of OsSUT1 and RSus3, a decrease of hexose to sucrose ratio and the initiation of starch accumulation. And last, strong expression of OsGPT1 and AGPP and active starch accumulation.

首先，在上粒和下晶粒中，Oscin1的表达以及甲基糖与蔗糖比的增加。其次，Ossut1和rsus3的表达，六糖与蔗糖比的降低以及淀粉积累的开始。最后，OSGPT1和AGPP的强烈表达以及主动淀粉的积累。
